possible 3.1.4 bug - echotc

possible 3.1.4 bug - echotc

[Paul Lew]

Just found out echotc behave differently on 3.0.[35] and 3.1.4:

$ echotc so | od -c			 3.0.3, 3.0.5, 3.1.3
0000000  033   [   7   m
0000004

$ echotc so | od -c			 3.1.4
0000000    n   o  \n
0000003

Bug or feature?

I've had problems with AIX, here, but judging from your domain, that's
not the problem.  If it's related... try searching for #ifndef
NCURSES_VERSION in Src/builtin.c, and changing it to #if 1.  If that
fixes it, we'll have to be more careful in testing for ncurses.

The above change fixes the echotc problem.  While doing this change, I
noticed a 'core' file in the root directory.  It is from 'conftest'.
which is generated by 'configure'.  Any trick to debug 'configure'?

I also got:

       zsh: bad math expression: unbalanced stack

when I tried the basic <TAB> on any directory.  I guess this might be
related to the conftest failure.

Thanks..

BTW, environment info:

zsh:		 3.1.4
OS:		 Digital UNIX 3.2c
Compiler:	 gcc -v

That's probably not a bug.  One of the configure tests is whether
tgetent() accepts a NULL pointer as the buffer argument.  The usual
behaviour if the answer is "no" is that one gets a segmentation fault
and conftest dumps core.  We should probably clean up the core file.
